You can find the Phase 5 Sloped Quick Disconnect End Plate here.

The Phase 5 Sloped Quick Disconnect End Plate for AR-15 has a built-in QD Sling Swivel. Built from sturdy 7075-T6 billet aluminum construction that is about 80% stronger than 6061-T6 aluminum. The aluminum construction weighs less than a standard stamped steel end plate (0.39 oz vs 0.48 oz). The QD mount is at a 30-degree angle from the lower receiver, which allows a 360-degree rotation for ambidextrous use. Uses a standard AR-15 carbine castle nut (not included) and is compatible with Mil-Spec and Commercial buffer tubes.
